HELP! Some nut is threatening to sue!

Due to my posts to sci.crypt and elsewhere that I was distributing PGP, I recieved the following, and after that a very biased textfile on the dangers of having PGP and how terrible it is. Can anyone verify that this is a real threat? Last I heard PGP *MIGHT* violate a patent, but that this had not been decided yet. Please reply soon, and by direct email. If it is the Real Shit, I don't think they are going to give me long to ditch PGP... :( Begin forwarded msg -----------------------------------------------------
